From "Bonze" Fleet on the Trojan:
"This small short cut face pusher is a must in the generic spread and will work very hard for you. This little demon will get smashed by anything that swims. Don’t let this lure fool you though. It has helped me catch a number of blue marlin over 500lbs and even a 650lb Bluefin tuna. Watch and then try and take your eyes off this one as it provides a multitude of strikes from a multitude of different species! Skirted Length: 305mm / 12” Hook Size: 9/0 – 10/0 Leader Size: 300lb – 400lb."
This particular head is from their "Custom" lineup with a blue rainbow-iridescent fish scaled wrap covering the insert with a set of red mirrored eyes. Skirted in blue with black bars/holo glitter and a green lateral line over green/chartreuse.
